Sao Paulo star Lucas admits rumours about Manchester United and Inter Milan are turning his head.

Lucas is being linked with United, Inter and Real Madrid this summer.

"I do not know yet whether I will stay until 2014 in Brazil, things can change," he confessed.

"The figures that I hear around my name, and the teams, make me think they have approached. For now I rest calmly and try to not let it affect me."
